943 F.3d 713
4th Cir.2019Background
- In April 2015 a 16‑year‑old ("L.") reported she had been trafficked for sex; investigation tied Raymond Aigbekaen to Backpage ads, hotel and rental‑car records, and surveillance.
- HSI learned Aigbekaen traveled abroad and alerted CBP to seize any electronic devices when he returned; on May 19, 2015 CBP seized his MacBook Pro, iPhone, and iPod at JFK and HSI performed warrantless forensic images.
- Forensic images revealed Facebook Messenger material and other data later relied on in warrants obtained in August 2015 for the same devices and online accounts; HSI retained the devices for multiple weeks.
- Aigbekaen moved to suppress evidence from the May searches; the district court upheld the searches under the border‑search exception and found HSI had at least reasonable suspicion; defendant was convicted after trial.
- On appeal the Fourth Circuit held the warrantless forensic searches were nonroutine and unconstitutional because the Government lacked individualized suspicion tied to the border‑justifications (no nexus), but affirmed under the good‑faith exception because officers reasonably relied on then‑existing precedent.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether warrantless forensic searches of digital devices at the border are permissible without suspicion tied to border purposes | Aigbekaen: border exception should not extend to intrusive forensic device searches absent a nexus to border justifications; warrants required for searches aimed at domestic crimes | Govt: border search exception applies at airport; agents had reasonable suspicion of trafficking and possible child porn so no warrant needed | Forensic searches are nonroutine; border exception requires individualized suspicion that bears a nexus to border purposes; no such nexus here => search unconstitutional |
| Whether agents had reasonable suspicion of contraband (child pornography) or transnational nexus | Aigbekaen: Government lacked particularized, objective basis to suspect child pornography or transnational component | Govt: had concern based on hotel manager tip and nature of sex‑trafficking; crime commonly involves cross‑border movement | Court: hotel tip was too vague/third‑hand to establish reasonable suspicion of child porn; no adequate evidence of transnational nexus |
| Whether later warranted searches and returns render dispute moot or supply an independent source | Aigbekaen: tainted evidence should be suppressed; Govt: later August warrants or returns supplied untainted source/mootness | Govt: August warrants obtained and returns used at trial; asserts independent‑source doctrine | Court: record lacks district‑court findings to show August warrants were independent sources (agents may have been prompted by May results), so independent‑source doctrine not established on this record |
| Whether the good‑faith exception bars suppression despite constitutional violation | Govt: agents reasonably relied on then‑binding precedent allowing border device searches; exclusionary rule inapplicable | Aigbekaen: lack of nexus means bad faith exploitation of exception | Court: good‑faith exception applies — officers reasonably relied on established precedent (pre‑Kolsuz developments) => suppression barred; conviction affirmed |
